How can error handling be improved in the given PHP code to identify and troubleshoot issues more effectively?

The issue with the current PHP code is that it lacks proper error handling, making it difficult to identify and troubleshoot issues effectively. To improve error handling, we can use try-catch blocks to catch exceptions and handle errors gracefully. Additionally, we can use functions like error_reporting() and ini_set() to set error reporting levels and display errors for debugging purposes. 

<?php

// Set error reporting level
error_reporting(E_ALL);

// Enable error display for debugging
ini_set('display_errors', 1);

try {
    // Code that may throw exceptions or errors
    $result = 1 / 0;
} catch (Exception $e) {
    // Handle exceptions
    echo 'Caught exception: ' . $e->getMessage();
} catch (Error $e) {
    // Handle errors
    echo 'Caught error: ' . $e->getMessage();
}

?>
